Spirometers are used globally to diagnose respiratory diseases, and most commercially available spirometers "correct" for race. "Race correction" is built into the software of spirometers. To evaluate pulmonary function and to make recordings, the operator must enter the subject's race. In fact, the Joint Working Party of the American Thoracic Society/European Respiratory Society recommends the use of race- and ethnic-specific reference values. In the United States, spirometers apply correction factors of 10-15% for individuals labeled "Black" and 4-6% for people labeled "Asian...

Lung cancer is one of the leading causes of cancer death worldwide. Surgical removal remains the best option for most tumors of this type. Reduction of cigarette consumption in patients with lung cancer candidates for the surgery could limit the impact of tobacco on postsurgical outcomes. Breathing exercises appear to help combat cigarette cravings. Yoga exercise benefits have been studied in lung cancer survivors, rather than in the preoperative setting. In this study, we have recruited 32 active smokers affected by lung cancer and being candidates for pulmonary surgery...

INTRODUCTION: Edentulism is one of the debilitating states affecting a significant portion of the geriatric population. It is often considered as the ultimate marker for predicting the pressure and burden on oral health. Respiration is also a routine vital function running continuously through the human body and most commonly assessed by a spirometer. Hence, we planned the present study to assess the impact of complete dentures on the functioning of the respiratory system. MATERIALS AND METHODS: In the present study, a spirometric assessment of the effect of complete dentures on respiratory performance was done...

The use of office spirometry was recommended by the National Lung Health Education Program (NLHEP) consensus conference in 1999 for detection and management of COPD. Since that time, spirometry utilization has increased, but its role in the diagnosis of COPD is still evolving. This update reviews the role of spirometry for screening and case finding in COPD as well as for asthma. Spirometry has been used for disease management in patients with airway obstruction, with varying results. The diagnostic criteria for COPD using spirometry have also evolved in the past 17 years, with differences arising between the Global Initiative for Chronic Obstructive Lung Disease and NLHEP recommendations...

Asthma and chronic obstructive pulmonary disease (COPD) patients are required to inhale forcefully and deeply to receive medication when using a dry powder inhaler (DPI). There is a clinical need to objectively monitor the inhalation flow profile of DPIs in order to remotely monitor patient inhalation technique. Audio-based methods have been previously employed to accurately estimate flow parameters such as the peak inspiratory flow rate of inhalations, however, these methods required multiple calibration inhalation audio recordings...

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a leading cause of mortality. Advances in remote technologies and telemedicine provide new ways to monitor respiratory function and improve chronic disease management. However, telemedicine does not always include remote respiratory assessments, and the current state of knowledge for people with COPD has not been evaluated. OBJECTIVE: Systematically review the use of remote respiratory assessments in people with COPD, including the following questions: What devices have been used? Can acute exacerbations of chronic obstructive pulmonary disease (AECOPD) be predicted by using remote devices? Do remote respiratory assessments improve health-related outcomes? MATERIALS AND METHODS: The review protocol was registered (PROSPERO 2016:CRD42016049333)...
